This recipe is really simple and quick to make and delicious to eat. I made it with Ling finish as did not have cod. I added cauliflower rice which I had grated in the last 5 minutes which made it a full meal.
Thannks Mary, so glad you enjoyed the recipe! Using Ling fish and adding cauliflower rice sounds like a brilliant twist—such a great way to make it a hearty, complete meal. Love your creativity! 👏✨
We love this meal and use any white fish and sometimes prawns was well.
We serve with roasted zucchini, cauliflower and asparagus.
